The adjusting device comprises a cylindrical support member that is mounted in the associated knife holder for rotation about an axis parallel with the first pivot axis. The circumferential surface of the support cylinder includes a plurality of segments that are selectively engaged by flat portions of the cutting blades, thereby to define different cutting profiles, respectively. The knife holder is connected for longitudinal displacement on one the clamping jaws of the tool handles, thereby to remove a severed length of the insulation layer from the insulated conductor. | 06-25-2009 |
20090188349 | Knife assembly for insulation stripping tools - A pliers-type insulation stripping tool includes a releasable fastening device for fastening a knife cassette to at least one of the knife carrier members that are longitudinally displaced by the pivotally connected tool handle members to remove a severed length of insulation from a longitudinally-arranged insulated conductor that is clamped between by the tool gripping jaws. A U-shaped resilient fastener spring wire has leg portions that are resiliently biased apart, at least one of the legs containing a laterally extending bulge portion that extends into a corresponding locking slot contained in a side wall of the knife cassette. To release and replace the knife cassette, the protruding free extremities of the leg portions of the spring wire are displaced together, thereby to remove the leg bulge portion from the slot contained in the cassette outer wall. | 07-30-2009 |
20110299246 | MODULAR ELECTRONICS HOUSING - A housing for protectively enclosing a printed circuit board, including a base, and a pair of parallel spaced vertical housing side walls extending upwardly from the base to define a chamber that receives the central portion of the printed circuit board, whereby the vertical edge portions of the board extend outwardly beyond the corresponding vertical edges of the housing side walls, respectively. Vertical side members having generally U-shaped horizontal cross-sectional configurations are mounted on the outwardly extending edge portions of the printed circuit board, respectively, with the leg portions of each side member extending between the housing side walls and the printed circuit board, respectively, whereby portions of housing side walls overlap the side member leg portions. The upper end of the chamber is closed by a lid member that is fastened between the upper ends of the side members. | 12-08-2011 |

20140048070 | RESPIRATORY DEVICE AND METHOD FOR CONTROLLING A RESPIRATORY DEVICE - A respiratory device having a respiratory gas source, a control unit and a connecting device for connecting to a respiratory mask. The control unit is connected to a sensor for detecting a measurement parameter. The control unit has a step generator for specifying a stepped modification of the pressure that is generated by the respiratory gas source. The sensor measures a signal that corresponds to the pressure distribution and is coupled to an analyzer that evaluates the temporal distribution of an analysis signal that is dependent on the measuring signal. The step generator increases the pressure by a pressure step in a respiratory cycle that follows the measuring evaluation, if the analyzer determines a deviation of the analysis signal from a limit value after a predeterminable time limit has elapsed following the pressure increase. The deviation must exceed a predeterminable minimum differential in order to trigger a pressure increase. | 02-20-2014 |
